One of the popular tricks used by players in esports is a quick change of weapons during reloading. Now you can use this technique with the help of a unique macro that I present to you. 

How it works: When your current weapon is completely discharged, just press the button on which you will link this macro. The macro will automatically take one shot and start reloading, simultaneously interrupting the animation of changing weapons, and returning the main weapon to your hands. 
Thus, you will be able to make a quick change of weapons at the most appropriate moment, minimizing the time that would be spent on animating the change of weapons. This can be useful in situations where you find yourself in close combat and you need to immediately repeat the shot to destroy the enemy.
